RadPdfProcessing is a processing library that allows creation, import and export of PDF documents.

The API of RadPdfProcessing contains two different editors, enabling you to choose between editing in a flow-like manner, or using the much more powerful and flexible fixed document structure and drawing on the page.

The document model of the library provides support for:

Pages: Adding, modifying or removing of pages in a document. The properties enable you to change the size of the page, its rotation and more.

Automatic layout: Although the PDF format is fixed, sometimes you will need to insert the content in a way that flows on the page. RadPdfProcessing enables to achieve this easily by using blocks, tables and lists.

Images: Decoded on demand to achieve better performance. The API enables you to obtain the encoded image data. You can also control the image quality when saving the document.

Form XObjects: The Form XObjects enables you to describe composite objects (consisting of text, images, vector elements, etc.) within a PDF file and reuse this content among the document, for smaller document size and better rendering performance.

Interactive Forms: Create and modify PDF files containing textboxes, buttons, listboxes and other interactive controls making available for the PDF file user to interactively fill some data in the PDF document and/or digitally sign the filled document.

PdfFileStream: The API exposes a functionality that provides option for exporting PDF files with unmatched performance and minimized memory footprint. Extremely useful when you need to add some content to existing document, merge or split documents.
